WIRE-SPRING FABRIC.

Specification of Letters Patent.

Patented June 18, 1907.

Application filed June 1, 1906- Serial No- 319,742.

1'0 all whom, it may concern:

Be it known that I, ALEXANDER G. CAM- ERON, of the city of WVinni eg, in the Province of Manitoba, Canada, uilder, have invented certain new and useful Im rovements in I/Vire-Spring Fabric, of which t 1e following is the specification.

My invention relates to improvements in wire spring fabric, more especially that adapted for the construction of bed springs and the like, and the object of the invention is to devise a simple, strong and durable construction of fabric, and it consists essentially of a series of inter-looped, locked strands of wire designed to be supported in a form all arranged and constructed as hereinafter more especially described. I

Figure 1, is a perspective view of several of the strands looped together and also showing a method of securing the adjoining outstanding ends. Fig. 2, is a perspective view of a single looped strand showing a modification of that used in Fig. 1. Fig. 3, is a side view of the means employed for fastening the adjoining ends previous to securing ermanently. Fig. 4, is a front view of the oint as in Fig. 3. Fig. 5, is a side view of the per manent joint formed at the ends.

In the drawings like letters of reference indicate corresponding parts in each figure.

A, is an individual length of resilient wire bent forwardly and backwardly upon itself in a sim le saw tooth wave form forming opposing oops, B C respectively, staggered, relatively, the one to the other. The uppermost series of loops B are simply plain bends in the wire, the loop remaining in the plane of the wiring forming the same. The lower series of loops C are formed by turning the simple loop into a plane at right angles to the plane of the u per loops and at the same time bending tie outstanding ends toward each other, forming a spring locking, receiving recess.

understood that they are formed alternately by a right and left hand turn of the wire.

In forming my fabric, a series of such bent wires are joined the one to the other the simple loop B being constrained within the loops C. The opposing outstanding ends of an interlooped set are fastened by means of a ferrule D, through the side of which is an opening designed to receive the ends D D of the said wires. In making the joints the wires are inserted in the ferrule D and it is flattened, thus turning the ends D D backwardly on themselves as clearly shown in Fig. 5. Although I prefer to use this joint, Iwish it to be understood that'the simple hooked joint may be used and also that the individual lengths of wire may be looped as shown in Fig. 2; the lower 100 s C of which are formed similarly to that C, *ig. 1, save that they are all formed by means of right hand turns of the wire.

It will be seen that I have invented a particularly, simple, cheap and durable fabric, which on account of its simplicity of formation and stability should prove itself invaluable in filling the requirements of such a fabric.

What I claim as my invention is As a new article of manufacture,a fabric composed of a series of individual lengths of wire inter-looped and securely inter-locking the one in the other, and means for fastening the outstanding ends of the inter-looped set, comprising a ferrule having an opening in the sides thereof to receive the said ends and designed to be flattened bending the ends upwardly and securing them therein as and for the purpose s ecified.
